A mum claims the smell is so bad in her home she has to 'hold her nose' to walk into her kitchen. Haby Ahama, 52, moved into her home, owned by Riverside Housing, in Kensington over four years ago.

I had to bag her groceries for her and she smelled very bad to the point ... My strategy was to just put my nose under my shirt and try to hold my breath so I don’t smell this awful smell.

Your sense of smell often alerts you to potential danger. Bad smells can serve as a warning that something is amiss. If it smells bad, it is probably bad for you. More often than not, the nose knows.

Humans can usually tell the difference between about 10,000 different smells. But if they’ve got a bad cold, all that snot blocking their nose might stop them from being able to smell at all.
